FLEXIBLE snmonn Application and october To (/72 whom it may concern:

Be it known that I, \ViLLIAM A. JOY, a

citizen of the United States, residing at.

Springfield, in the county of Sangamon and State of Illinois. haveinvented a new and useful Flexible Shingle, of which the following is aspecification.

My invention relates to improvements'in curling ofthe shingles and atthe same time morals desi nate the maintain the symmetricaldiamond-shape arrangement of the laid" shingles.

I attain this purpose by the means illustrated in the accompanyingdrawing in which Figure 1 is a top plan of part of a roof covered withshingles embodying my-invent-ion; Figure 2 is an enlarged top view of asingle detached shingle; Fi 3 is an under-side view of the same detacled shingle; Fig. 4- is an enlarged vertical section taken on the line4-45 of Fig. 3; Fig. 5 is an under-side view of'a shingle of modifiedconstruction embodying my invention; Fig. 6 is an enlarged verticalsectiii' taken on the line (36 of Fig. 5; and Fig. 7 is an; endargedvertical section taken on the line 7-4 of Fig. 5. The same I referencenusame parts in all the views. 1

The shingles 8 are preferably" of asbestos composition and each shingleis square am has four right-angle corners in order that the symmetricalarrangement shown in Fig. 1 may be maintained when the shingles are laidon the roof. A starter-strip 9 consisting of flexible roofing of thesame material I as the shingles is laid along'the lower edge,

of the roofs Parts of the first, second and third rows ,of shingles lieon the sta rter strip. Thepfirst or bottom row will corisist ofapproximately half-shingles; all the other rows will consist of wholesquare shingles of uniform size. One shingle of preferred constructionis shown inFigs. 2, 3 and 4. On the' underside of the shingle is atriangular flap or fastening member 10 of the same material as the bodyof the shin gle. The edges of the flap which converge at itsright anglecoincide with the converging ed es of thelower end of the shingle.

. The asbestos composition of the shingles is 7, 1924. Serial No.742,179.

naturally sticky. There is practical advantage in making the flap 10 ofthe same ma terial. The advantage is that the movable members of theflap, hav'ing considerable contact ,area will adhere to the interlockingshingles and will soon after laying, become practically cementedthereto, thus preventing the breaking or pulling out of the flap.

There is also practical advantage. in the form of the flap, in that itaffords larger cgntact area than has hithertobeen availale. V

A filler or spacer 12 of the same material as the body of the shingle isinterposed between the flap 10 and the shingle-body 8.

A staple 13 extends through the flap,.

through. the spacer, and through shingle- -b0dy and isclinched onthe-upper side ,ot' the shingle and unites the parts firmly. The len thof the body of the staple is in a diagona lower corners of the shingle.

is preferably of the samethickness as the shingle and the inclined upperedges of the spacer serve as guides in placing the adjacent shingleswhich are overlapped by the. shingle in question. The particularposition of the staple, in a diagonal line of the shingle, is ofimportance'because it facilitates manual adjustment of the freecorn'er-* members 18 of the flap '10 relative to the bodylof the shingleso that the adjacent parts 'of the interlocking shingles "may be easilyinserted: in the sphco between the shingle body andthedlap: The flapnc/hr l bet-10 and the spacer 12 are omitted from the shingles which areused in the first row of whole shingles and the lower ends of theshingles in said first row are connected with the half-shingles bycement 14.

In laying the shingles on the roof, beginhave no flaps and mo spacers'and t'he lower Will he corners of the respective shinglcs secured onthe half-shingles by cement The shingles will. he larlrifin her-conicalline connectingv the upper and, The spacer l2" hing at the lower edge.of the starter strip,

, next lower courses each course comprising a number of shingles placedwith, their right and left,

-with'each other along the lower edge of the starter strip.- The firstcourse of whole shingles will be placed with their right and leftcorners in line with each other and the respective shingles will besecured by nails 15 at the uppercorners of the shingles. Thewhole-shingles comprised in the second course will be placed with theirright and left corners in line with each other and their lower marginsoverlapping the upper margins of the adjacent two shingles of thecourse. Before nailing the shingles of the second course each shingle ofthat course will he moved upwardly to cause the flap memhers 18 of theflaps 10 of the respective shingles to underlie the two adjacentshingles of-the next lower course and when the shingles have beeninterlocked as described a nail 15 will be driven through the uppercorner of each shingle in the course to'hold it in place: and eachsuccessive course will he placed and secured in like manner.

Relatively thick shingles are used in the preferred construction shownin Figs. 1, 2,"

3 and 4 and described ahovef I have found by experiment thatifrelatively thin shingles areused the construction shown in Figs. 5, 6,and 7 a'nd'now to be described gives very satisfactory resuits.

The shingle 19 is thinner than the shingle 8 but in all other respectsis the same as that shingle. Theflap 20 is the same as the flap 12except .as to thickness and the converging inclined edges of the flapcoincide with the inclined converging edges of the shingle. The freeterminal members 21 of the flap 20 are similar to the termimile 18 ofthe flap 10. Dotted lines 22 Fig. 7 indicate the manually adjustedposition of the members 21 relative to the shingle body 19.

A staple 23 coincides with a diagonal line of the shingle body andextends through the flap and the body and is clinchedfl on the upperface of the shingle. 'The procedure in laying the modified shingles isthe same as in laying the shingles of preferred construction.

I am aware of the prior'use of shingles having bent-under flaps providedwith laterallyextended metal strips which engage the adjacentinterlocking shingles, but that construction is objectionable becausethe bend of the turned under part-gives the shingle the appearance ofbeing cut off and ners: a triangular flap of the same the cut offappearance detracts fromv the symmetry of the diamond arrangement of theshingles on the roof.

Inmy construction the at ractive diamond arrangement of the shingles isintact on the whole of the roof. Another feature of my improvement isthat the converging edges of the flap coincide with the converg ingedges of the body of the shingle, the spacer facilitates the interl kingof the shingle and there is no nece to use any 'n'ietalstrip', or anyother extraneous iuterlocking member. This improved and simplifiedconstruction is 0t practical \Zt 0 because it ados to the attractiveappearance of the roof as a whole. less expo and more convenient tohandle th shingle having a metallic or other emit ous interlockingelement.

.I am also aware of the prior use shingles notched atythe lower cornersuch notched shingles are subject to th same objection of marring theappearai of the diamond arran inent of the shingles on the roof.

Having fully described my invention,

"what. I claim as new and desire to secure by Letters Patent is:

1. A flexible shingle comprising a Hat square body having fourright-angle corterial as the shingle body and having verging inclinededges coinciding with the converging inclined edges of the body: aspacer ot' the same material interposed be tween the; shingle body andthe having inclined upper edges effective o guide theplacing-ofinterlocking shingl and a staple in line with a. diagonal 0 he. body andextending through the flap, 1h: spacerg' and the body and clinched onthe upper face of the body to unite the parts firmly.

2. A flexible shingle comprising 2 rectangular body of flexible mattriangular flap of the same'maierial converged edges coinciding with theverged edges at the right angle of the corner of the body. also havingfree lar terminal members serving as interlocking means and adapted tocling to inter-- locking shingles and manually movable relative to theshingle-body; a spacer ot the same material as the shingle body: and alllfi-
